EPF10K100ARI240-3N 概覽

The Intel (formerly Altera) EPF10K100ARI240-3N is a 100,000-gate FLEX 10KA family Field-Programmable Gate Array (FPGA) housed in a 240-pin RQFP (32x32 mm) exposed-pad package. The device integrates 4,992 logic cells, 24,576 RAM bits, and 189 user I/Os, fabricated on a 0.30 µm CMOS SRAM process with 3.3 V core supply and a 3.3 V I/O bank. Speed grade -3N designates a -40 °C to +85 °C industrial temperature range with the standard (non-A grade) timing.

What is an FPGA? An FPGA (Field-Programmable Gate Array) is a programmable logic device whose logic fabric, routing, and I/O cells can be configured by the end user via a hardware description language such as VHDL or Verilog. Within the broader taxonomy of integrated circuits, FPGAs sit between CPLDs (smaller, non-volatile) and ASICs (custom-silicon, high NRE). The FLEX 10KA family was the industry's first embedded programmable logic family, providing System-on-a-Programmable-Chip (SOPC) integration by combining an embedded array block (EAB) for megafunctions and memory with a logic array block (LAB) fabric. The EPF10K100A is the largest-density member of the family.

Key features of the EPF10K100ARI240-3N include MultiVolt I/O (supporting 2.5 V, 3.3 V, and 5.0 V interface levels on a per-pin basis via VCCIO), PCI-compliant clamping diodes with slew-rate control, individual open-drain output options, and dedicated global clock networks. The embedded array blocks deliver efficient on-chip memory, typically configured as 4,096-bit RAM per EAB. Combined with 624 LABs, the device supports up to 125 MHz internal operation and approximately 100,000 typical gates (4,992 logic elements).

Typical applications include glue logic and bus bridging in industrial controllers, telecommunications backplane interfaces, PCI bridge prototyping, and legacy system refresh designs where the FLEX 10KA silicon is already qualified. The RQFP-240 footprint has been in continuous production since the late 1990s, and Intel/Altera continues to ship the part for long-lifecycle programs in medical, defense, and industrial automation.

When designing with this FPGA, allocate adequate decoupling (100 µF bulk + 0.1 µF per VCC/VCCIO pin pair) and a minimum of four-layer PCB with dedicated power and ground planes. Use the Quartus II 13.0sp1 (the final version supporting FLEX 10KA) for design entry and ACEX 1K / FLEX 10K device programming via ByteBlasterMV or a compatible JTAG cable.

This page synthesizes distributor pricing, FLEX 10KA drop-in alternatives, and practical legacy-design notes not consolidated in the original manufacturer datasheet, helping engineers plan both new designs and long-term maintenance of installed bases.

🏭

Industrial PLC and Factory Automation Controllers

The EPF10K100ARI240-3N is well-suited for legacy industrial PLC and factory automation controllers where its 100,000-gate capacity, 189 MultiVolt I/Os, and -40 to +85 C industrial temperature range directly match the harsh factory-floor envelope. The device typically glues together sensor I/O, stepper/servo PWM generation, and Modbus/Profibus interface logic on a single programmable device. Its PCI-compliant I/O cells simplify integration with industrial backplanes and PC/104 SBCs, while the 24,576-bit embedded array block delivers distributed on-chip scratch memory for closed-loop control loops. Replacement of the controller CPU is non-trivial, so the FLEX 10KA's long production history is an asset for factory-floor retrofits running 10-15 year lifecycles.

🌐

Telecommunications Backplane Bridging and TDM Multiplexers

The EPF10K100ARI240-3N is widely deployed in legacy TDM (T1/E1/DS3) multiplexer and backplane-bridging designs where its 4,992 logic cells and dedicated global clock network deliver deterministic timing for 8.192 Mbps and 16.384 Mbps time-slot interchange fabrics. The 189 I/Os give telecom designers ample headroom for low-voltage TTL interfaces to LIUs (line interface units) and framers, while MultiVolt I/O at 2.5 V, 3.3 V, and 5.0 V lets a single FPGA bridge mixed-voltage backplane segments without external level shifters. Long production continuity is critical for telecom OEMs with 20-year service-level commitments.

PCI Bus Bridge and Industrial PC Add-in Card Designs

The EPF10K100ARI240-3N's PCI-compliant clamping diodes, slew-rate control, and 5 V-tolerant MultiVolt I/O make it an ideal PCI bridge or PCI target device in industrial PC and add-in card designs. Designers typically implement a custom PCI interface plus an application-specific payload core within the 4,992 logic cells, achieving 33 MHz PCI operation with predictable timing at the -3N speed grade. The exposed-pad 240-RQFP package provides sufficient thermal margin for continuous 33 MHz bus operation in industrial chassis. Modern boards requiring 66 MHz PCI-X or PCIe must migrate to newer Cyclone families; the EPF10K100ARI240-3N is recommended only for legacy PCI maintenance.

選型指南

Choose the EPF10K100ARI240-3N when your design requires industrial temperature operation (-40 to +85 C) in a FLEX 10KA family part, the medium -3 timing bin is acceptable, and you need a 240-RQFP exposed-pad footprint. For faster internal timing at industrial temperature, choose the EPF10K100ARC240-1N (speed grade -1). For commercial temperature (0 to +70 C) lab or office environments, the EPF10K100ARI240-3 or EPF10K100ARC240-1 are drop-in alternatives at slightly lower cost. All six pin-compatible variants share the 32x32 mm 240-RQFP land pattern, enabling single PCB design across temperature and speed grades. For new designs requiring higher logic density or modern transceivers, migrate to the Intel Cyclone IV or Cyclone V families in different packages - this requires a full PCB redesign.

設計說明

Estimated: With VCCINT at 3.3 V and a typical FLEX 10KA Iccint of 100 mA quiescent plus 5 mA per active logic cell at full utilization, the EPF10K100ARI240-3N draws approximately 250-400 mA from VCCINT depending on toggle rate and clock frequency. VCCIO banks consume an additional 5-15 mA per bank depending on switching I/O load. Place a 100 uF bulk capacitor within 25 mm of the package and a 0.1 uF ceramic bypass on every VCCINT and VCCIO pin pair. Insufficient decoupling on VCCIO causes MultiVolt I/O logic-level drift and can corrupt PCI bus transactions.

The 240-RQFP exposed-pad package requires a 32x32 mm PCB land pattern with a center exposed pad of approximately 6x6 mm. Solder the exposed pad to a flooded copper pour on the top layer with at least 9 thermal vias (0.3 mm drill, 0.5 mm pitch) to an internal ground plane. Without the exposed-pad solder connection, junction-to-ambient thermal resistance rises 40-50% and may cause thermal shutdown at elevated ambient temperatures in industrial environments.

Do not connect VCCIO to a voltage greater than 5.0 V or less than 2.5 V - this violates the MultiVolt specification and may damage PCI clamping diodes. Always assert nCONFIG low for at least 1 us after VCCINT and VCCIO rails reach regulation before starting configuration. Use the dedicated ByteBlasterMV or USB-Blaster download cable - parallel programming via the legacy EPC1/EPC2 configuration EPROM is not supported on FLEX 10KA. For JTAG boundary-scan, ensure TMS and TDI have valid logic levels during power-up; floating JTAG inputs may cause unintended BYPASS register shifts.

Route global clock inputs (CLK0-CLK3) on the inner PCB layer with 50 ohm controlled impedance and length-matched to within 1 mm across all four clocks. When using the EPF10K100ARI240-3N as a PCI bus master or target, route the 32-bit PCI bus segment within 50 mm and match each AD bus trace to within 2 mm. Place a 22-33 ohm series-termination resistor near the FPGA driver for clock traces above 50 MHz; this reduces over/undershoot that violates PCI AC specifications at -3N timing.
